STOVE.

Specification of Letters Patent No. 25,579, dated September 27, 1859.

To all whom it may concern:

Be it known that I, OSCAR PADDOCK, of Watertown, in the county of Jefferson and State of New York, have invented a new and Improved Stove; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 represents a longitudinal vertical central section of my invention. Fig. 2 is a front view of ditto. Fig. 3 is a horizontal section taken in the line 00, 00, Fig. 2.

Similar letters of reference in the three views indicate corresponding parts.

The object of this invention is to prevent the smoke from the interior of the stove passing into the room, or house, when the door is opened; and it relates to an improvement in that class of stoves in which the draft passes through the whole length of the shell of the stove, and up through a tube in the back end of it into a drum, the front end of which communicates with a fine so that the pipe leading from the stove into the chimney is situated right over the fire place; and this invention consists in arranging, right over the fire place, and in front of the stove an extra communication between the interior of the stove and the drum, which is effected by means of a tube the mouth of which is closed by a damper which is connected with the furnace door in such a manner, that by opening the door the communicating passage is also opened, so that the smoke from the fuel passes straight up into the chimney as soon as the door is open, said passage being closed as long as the door remains shut.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A represents the shell of a stove which is constructed of sheet metal, or of cast iron, or it may be made of any other substance applicable to stoves. A transverse vertical section of this stove shows the form of an egg, and it is smaller at one end than at the other, whereby the fire is more effectively contracted, and the plates used for this shell are corrugated so as to obtain the largest possible radiating surface. The front end of this shell is closed by a door, B, which opens to the fire'place; and the back end of the shell communicates, by means of a pipe, a, with a drum, C, which is secured on the top of the shell, A, eXtending from one end of the same to the other, and its front end communicates with the front end of the shell by means of a pipe, 6, similar to the pipe, a; and these two pipes serve at the same time to support the drum. The mouth of the pipe, Z), is closed by means of a valve, or damper, c, which slides in guides, cl, at tached to the bottom of the drum, and a rod, 6, extends through the end of the drum, connecting by means of a link, 7", with a lever, g, which is fulcrated on a standard, h, secured to the end of the shell above the fire door, 13. One end of this lever is considerably shorter than the other, and its short end forms a fork, i, which embraces a pin or rod, is, which is rigidly attached to the door as clearly represented in Fig. 2. The front end of the drum communicates with the flue or chimney by means of a pipe, Z.

As long as the door is closed the valve or damper, 0, closes the mouth of the pipe, Z), and the draft from the fire in the front end of the shell has to pass through the whole length of the shell to the pipe, a, and up into the drum, and through the whole length of the same to the pipe, l, in order to reach the chimney. As soon, however, as the door, B, is opened the rod, 70, strikes against the fork, i, throwing the short end of the same out, and the damper is caused to slide from over the mouth of the pipe, Z2, leaving the smoke, arising from the fuel in the fire-place, a free passage right straight up to the pipe, Z, and through this pipe to the chimney, so that no smoke comes out by the door, which would fill the room, or the house to the great inconvenience of its inmates. As soon as the door is closed, the valve or damper is brought back to its original position by the action of the rod, 70, and the draft is restored to its original circulation.

It is obvious that the arrangement of this valve is equally applicable to all kinds of stoves in which the smoke, arising from the fuel, has a tendency to pass into the room when the door is opened.

What I claim as new, and desire to secure by Letters Patent, is

The damper, 0, arranged over the pipe, 6, through which a direct communication be- 5 tween the fire-place and the chimney is effected, and operated by means of a rod, 7:,

or its equivalent, which is secured to the I door, B, and which acts against EL- forked lever, g, substantially as and for the purpose specified.
